My mom’s best friend has been knitting for 40+ years and has made all kinds of fancy things. She tried Lion Suede last year and gave up on it. I think she gave the yarn away. If it is Berroco Suede, you might be in better shape but I still wouldn’t want to learn on it.
Learning to knit is a little like learning to drive a stick-shift. It can be tricky at first, but once you get the feel of it, you can’t believe you ever didn’t get it. And, if you try to learn on a car with a tricky clutch, you will get very frustrated because the car will be giving you all the wrong signals. The suede yarn is the same way. Once you get the feel for how knitting is supposed to feel, you can move back to the suede.
I learned on Lion Brand Wool Ease, which I recommend for learning. But almost any basic yarn, Red Heart, Red Heart Soft, Caron Simply Soft, will be better than the suede yarn.
I will say that knitting with a tricky yarn early on can help in some ways. I remember that a few days after I learned to knit, I tried to knit a little with Pattons Allure, which is the eyelash yarn from hell (very pretty for a novelty yarn, but IMPOSSIBLE to see you stitches). That brief experience helped me understand how to read my knitting. Or rather, it helped me understand that I had been “reading” the wool ease, but was not really able to read the allure.
Anyway, don’t blame yourself. Get a regular 'ole yarn and spend a few days with that before moving back to the suede.
